Xavier Sal, Infested Captain + Intruder Alarm + Staff of Titania + Soul Stair Expedition

Xavier Sal, Infested Captain

Intruder Alarm

Staff of Titania

Soul Stair Expedition

How it works

1. Activate Xavier Sal by tapping it and removing a counter from a permanent you control, creating a token copy of the Forest Dryad token.
2. When the Forest Dryad enters the battlefield, Intruder Alarm and Soul Stair Expedition trigger.
3. Resolve the Soul Stair Expedition trigger, putting a counter on a creature you control.
4. Resolve the Intruder Alarm trigger, untapping all creatures.
5. Repeat.

This elegant engine turns a simple forest-dweller into an unstoppable loop by letting Xavier Sal, Infested Captain leverage the steady stream of tokens from Staff of Titania. Every time Xavier populates a new Forest Dryad token, its arrival triggers Intruder Alarm to untap your entire board, allowing Xavier to tap and repeat the process indefinitely while fueling massive landfall triggers for Soul Stair Expedition.
